MINERS CAP.

Speciication of Letters Patent.

Patented J une 3, 1919.

Application filed December 6, 1918. Serial No. 265,584.

To all 'wh-0m t may concern Be it known that I, MICHAEL J. GrroNs, acitizen of the United States, residing at Shenandoah, in the county ofSchuykill and State of Pennsylvania, have invented new and usefulImprovements in Miners Caps, of which the following is a specification.

In mines, injuries are frequently inflicted to the miner by pieces ofcoal falling directly upon his head. This is true especially when theminer is engaged in dressing down shots and placing relief timber. FromeX- perience I have found that such liability to injury can be avoidedby providing a protective disk for the ordinary construction of miners7caps, and it is the object of the present invention to produce aprotective device of this character which shall be of a comparativelysimple construction, easily applied to the cap when the miner is at workand readily removed therefrom to relieve the cap from the added weightthereof, when desired.

The drawings illustrate a simple and satisfactory embodiment of theimprovement reduced to practice, and in which:

Figure l is a general view illustrating the improvement Fig. 2 is asectional view approximately onthe line 2 2 of Fig. l;

Fig. 3 is a perspective view of the improvenient looking toward theunder face thereof; and

Fig. 4 is a similar view of the strap member designed to besecured tothe cap for removably supporting the protector thereon.

In the drawings I have illustrated a miners cap of the ordinaryconstruction which is designated by the numeral 5. On this cap I securea strap 6. The strap is arranged over the top of the cap and is bentagainst the sides of the cap. The strap is constructed of metal ifdesired, but may be formed of other material if desired, and the bent orangle ends 7 thereof are riveted or otherwise secured to the sides ofthe cap 5. Each of the sides 7 is provided with a transversely arrangedloop 8, the purpose of which will presently be apparent, and the centerof the strap is preferably widened, as clearly illustrated by thedrawings. On

this widened or enlarged portion 8 of the strap rests a hollow disk 9that is centrally secured to the inner and concaved face of theprotector l0. The protector is in the nature of a saucer shaped disk andhas its edges provided with diametrically opposed downwardly eXtendingfingers 11 that are adapted to be received in the loops of the strap,when the device is in applied position. If desired, the protector may beslit radially from the edge to a point adjacent the center thereof toadd to the resiliency of the construction, and the hollow disk in thecenter thereof provides an air cushion between the protector and the topof the cap, so that the protector will yield, -when contacted by flyingcoal or other obstacles and not inflict injury to the head of the wearerof the cap.

It is believed, from the foregoing description, when taken in connectionwith the drawings, that the simplicity and advantages of theconstruction will be readily apparent.

Having thus described the invention, what is claimed as new, is

1. In combination with a miners cap, of a strap arranged over the topthereof having a central widened portion and angle sides secured to thesides of the cap, said angle sides having transverse loops, a yieldabledisk adapted to be arranged on the top of the cap, cushioning meansbetween the center of the disk and the widened portion of the strap, andfingers on the disk adapted to be received in the loops of the strap.

2. In combination with a miners cap, of a strap arranged transverselyover the top thereof, said strap having a central enlarged -portion andangle ends that are secured to the sides of the cap, loops on said angleends, a compressible disk adapted to be arranged over the' top of thecap, an air cushion carried by said disk and engaging with the widenedportion of the strap, and fingers on said disk designed to be receivedin the loops of the strap.

In testimony whereof I affix my signature.

MICHAEL J. GIBBONS.
